Rey flnder0, 5 J Aftorne ya Patented Mar. 7, 1933 RAY ANDERS, OF INDIANAPOLIS, INDIANA APPARATUS FOR FORMING REMOVABLE ICE CREAM WBAPPERS Application filed April 22,

This invention relates to means for forming removable wrappers for ice cream and is a continuation in part of my application filed in the U. S. Patent Ofiice April 1, 1931, Serial It is a primary object of this invention to provide a mechanism for rolling wrappers into a conical form.

A further important object of the invention is to provide means for holding a wrapper in a formed position to have edges overlap and the formed position maintained without the use of adhesives.

A further important object of the invention is to provide means for pushing a formed wrapper having lapped free edges into a filling receptacle without permitting the wrapper to become opened up.

These and other important objects including the various novel and useful combinations of the elements entering into the mechanism employed as will be specifically pointed out at the end of the specification, will become apparent in the following description of the invention as illustrated in the accompanying drawings, in which Fig. 1 is a top plan view of a structure embody-Lug my invention;

Fig. 5 an end elevation on an enlarged scale of the head;

Fig. 6 a section longitudinally of the head and its supporting pipe of Fig. 5; and

Fig. 7 a wrapper blank.

Like characters of reference indicate like parts in the several views in the drawings.

On a suitable base 10 I mount a ring 11 to be in a vertical plane and secure thereto at points equi-distant therearound the outer 5 ends of the three shafts 12, 13 and 14, on

which shafts are revolvably mounted the conical blocks 15, l6and 17, respectively. The shafts 12, 13, 14 are carried rearwardly to have their ends supported by the standard 18 extending vertically from the rear end of 1931. Serial No. 531,910.

the base 10. The three cones 15, 16, 17 are of exactly the same shape and have their axial shafts 12, 13, 14 in parallel alignment.

Washers 19 are fixed on the shafts 12, 13, 14 at the rear of the blocks to prevent longitudinal movement of the blocks therealong. The base ends of the cones are toward the washers 19 and the forward ends of the cones abut the ring 11. Each of these cones are in reality frustrums in that each is cut off at its upper end in order that it may termimate in a surface to bear against the ring 11.

, On the standard 18 is secured a bracket 20 having a forwardly extending leg to which is pivotally attached a table 21 adapted to be swung toward and away from under the upper cone 14. This table 21 has an upturned flange 22 around its rear and outer edges and is shaped to receive snugly thereon a wrapper '23, Fig. 7. This wrapper is here shown as having a major arcuate edge from one end of which edge extends a side along a radial line to the center of curvature of the edge, and from the other end of which edge extends a side by a straight non-radial line directed outwardly from the center, and from the end of the straight line arcuately around to the outer end of a short radial line extending from the center in a direction away from the major edge.

Referring now to Figs. 5 and 6, I form a head which has a hollow body 24 with a frustro-conical boss 25 extending from its underside. A pipe 26 leads from the body 24 to any suitable air exhausting means 27 here shown as a fan operated by a motor 28. A hollow cone 29 is rotatably attached to the underside of the body 24 and has an upwardly extending conical flange adapted to surround the boss 25. A collar 30 rotatably connects the cone 29 with the body 24 and is formed to permit the cone to travel toward and away from the body 24 in such a manner that when the cone 29 is moved toward the body, the inner side of the upper flange will contact with the conical surface of the boss 25 whereas when the cone 29 is moved away from the body 24, the cone 29 may be revolved freely without rubbing by its upper flange over the boss 25. A central shaft 31 slidably extends through the collar 30 to have its upper end project to within the body 24 and carry a friction disc 32. A compression spring 33 surrounds the upper end of the shaft 31 and bears between the collar 30 and the upper outturned end of the shaft so as to normally prevent longitudinal travel of the shaft 31 downwardly through the collar.

The lower end of the shaft 31 has a square cross section and is slidably fitted within a correspondingly formed bore through the apex of the cone 29 whereby the shaft 31 may move longitudinally through the apex but will turn the cone 29 upon rotation of the shaft. The lower end of the shaft 31 is preferably rounded to form the tip 34 the lower end of which is held flush with the lower end of the cone by the spring 33 normally pushing upwardly on the shaft.

The upper end of the shaft 31 is provided with a bore into which extends the lower end of the rod 35 about which is rotatably carried a bevel gear 36. The rod 35 projects slidably through the upper side of the body 24 and carries a button 37 on its upper end. The underside of the gear 36 is provided with a suitable friction surface against which the disc 32 is normally pressed by the spring 33. A bevel gear 38 is in mesh with the gear 36 and is driven by the shaft 39 which extends therefrom through the pipe 26 back to theshaft of the motor 28 to be revolved thereby. Both the pipe 26 and the shaft 39 are made of flexible material to permit movement of the head in relation to the motor 28. A relief valve 40 is provided in the pipe 26 adjacent the body 24 and is normally held closed by means of the spring 41 surrounding the pin 42 extending outwardly therefrom, on the outer end of which a button 43. The cone 29 is provided with a plurality of holes 44 therethrough and openings are provided through the upper end of the cone 29 and through the underside of the boss 25.

In operating the structure above described, a wrapper 23 is positioned on the table 21 as indicated in Fig. l and the table is swung from the dotted line position around to the full line position to present the radial side of the wrapper tangentially against the underside of the 'cone 14, the table 21 being so formed and so mounted on the bracket 20 as to have this radial side coincide with an element of the cone 14.

The motor 28 is set in operation to cause the fan to exhaust air from within the cone 29 through the body 24 and pipe 26 and discharge it out the exhaust pipe 45 of the fan. Since the cone 29 is perforated, the degree of vacuum within the cone 29 is very slight. This vacuum is further reduced by pressing the button 43 to open the valve 40 and permit air to be drawn directly into the pipe 26.

The cone 29 is being revolved by the motor 28 through the shaft 39, gears 38 and 36,

clutch disc 32 and shaft 31. The revolving cone .is thrust through the ring 11 and the button 43 is released to increase the degree of vacuum within the cone 29 as the cone comes into contact with thethreeblocks 15, 16 and 17, whereupon the three blocks are then revolved by their rolling contact with the cone 29 to cause the edge of the wrapper 23 to be pulled around in the direction of rotation of the cone 29. Since the cone is perforate and air rushes through the holes into the cone, the paper wrapper 23 will be drawn against the outer side of the cone 29 and there held by reason of difference in pressure between the inside and outside of the cone. The wrapper thus follows around the cone 29 as it is revolved and is finally wrapped completely therearound whereupon the cone is withdrawn and carried over to above some suitable receptacle 46, Fig. 4. During the travel of the paper wrapper 23 around the cone 29, accidental displacement of the paper away from the cone is prevented by reason of the guards 47, 48 and 49 disposed between the conical blocks in such a manner that any projecting edge of the paper is directed around toward the surface of the cone 29 and between the blocks.

The cone revolving with the wrapper 23 held thereon by the vacuum within, is lowered to within the receptacle 46 and pressed downwardly thereih to cause the cone to bear firmly against the wall of the receptacle through the wrapper and permit the body 24 to be moved to have the boss 25 contact with and frictionally engage within the flange about the upper end of the cone 29 so as to stop the turning of the cone and permit thelwrapper to come to rest within the receptac e.

At the same time the boss 25 frictionally engages with the flange of the cone 29, the clutch disc 32 slips over the frictional surface on the underside of the gear 36, the pressure of the spring 33 being thus overcome. Now to disengage the cone 29 from the wrapper 23 within the receptacle 46, the button 43 is depressed to open the valve 40 and allow the pressure within the cone 29 to increase and at the same time the button 37 is depressed to force the tip 34 downwardly from out of the end of the cone 29 to bear against the inner'end of the wrapper 23 and hold it against the bottom of the receptacle 46. As the button 37 is depressed, the body 24 and cone 29 is lifted while the button 43 remains depressed also so that the cone then is entirely free from contact with the wrapper 23 and is removed vertically therefrom leaving the wrapper within the receptacle 46 with its edges overlapped and the lower end or point of the wrapper being slightly crushed to pro ject laterally through the spaces between the turns of the spiral wire which defines the shape of the receptacle 46.
